About this map

Mississippi Sound and Chandeleur Sound meet at the maritime border of Mississippi and Louisiana, a region defined by shifting shoals and low-lying marsh keys. The northern extent of the map features the western tip of Cat Island, including West Point, which falls within the protected boundaries of the Gulf Islands National Seashore. This environment is a complex network of navigable channels like Pass Marianne and the Intracoastal Waterway, crucial for coastal transit.

Further south, the landscape transitions into the fragmented islands and banks of St. Bernard Parish, Louisiana. Distinctive landforms such as Isle au Pitre, Creole Gap Key, and the curiously named Potato Hills emerge from the shallow waters. These features, along with submerged hazards like Pistol Bank and Cabbage Reef, illustrate the precarious and ever-changing nature of the Gulf Coast's barrier island systems.
